1 DR. HECKER: You get the addition. In general, you have the same 



2 species that you see on the slope; you see them also in the canyon but 



3 you get the addition of another suite of fauna on top of that. 



4 DR. MACIOLEK: So, you don't want to say you have-- 



5 DR. HECKER: I don't want to say you have replacement, per se. 



6 DR. MACIOLEK: You don't want to say that the species composition 



7 is different in the canyons. 



8 DR. HECKER: Composition, depending on how you want to define 



9 composition. Percentage, yes. You have a shift of percentages. 



10 DR. MACIOLEK: That's the same thing that I saw for the infauna, 



11 as well, the same species, slope and canyon, but percentage 



12 representation was different. 



13 DR. COOPER: Barbara, didn't you mention a species or two 



14 yesterday that were distinctive of the deeper portions of the canyons or 



15 did I misinterpret you, that were not part of the slope? 



16 DR. HECKER: Oh, yes, deep in the canyon, yes. You've got various 



17 starfish, the, the filter-feeders, you've got a variety of corals down 



18 there. 



19 The problem with deeper with regard to the way we analyzed our 



20 data, which would be with the community analysis, is that because the 



21 brittle star, is so common, that the contribution of the other organisms 



22 is just sort of masked, but they are there. 



23 DR. COOPER: Aren't there several species, based on your work, 



24 primarily, that are distinctive only to the canyon environments? Is 



25 that a true statement or is that not true? 



26 DR. HECKER: Several species distinctive only to the canyon 



27 environment? Have I never, ever seen those corals on the slope? No, I 



28 cannot say that. However, I may see one or two in a whole slope area 



29 and I will have seen 100s in the canyon. 



30 DR. COOPER: Relatively speaking, distinctive to the canyons. 



31 DR. HECKER: Relatively speaking, distinctive to the canyons. 



32 Most of those corals, I would say about 90 percent of those corals, are 



33 distinctive to canyons. There are only several sea pens that are not 



34 distinctive to canyons.
